I am building a covered 12x12 enclosed area with a roof on top of the whole thing, three sides have 4 ft of galvanized tin on the bottom half and hardware cloth 2 1/2 ft to the roof. 4th side will be hardware cloth only. I live in sunny FL. Inside this are I will attach a roost bar and nesting boxes so it's the coop and run are together all in one . How many chickens can comfortably be in there? They will not free range but they will get grass, herbs and veggies/fruit daily inside the enclosure. I know it's 3-4 ft for coop and 10 sq ft for run, but I'm confused with it being an all in one. Thank you for reading! This is someone else's pic but I'm doing something similar. Mine will have hardware cloth in top not tin all the way up and mine slants to the open hardware cloth end with a long overhang.
